摘要： An air-fuel ratio controller which detects oxygen content of the engine exhaust gases, compares the detected value with an objective oxygen content corresponding to an objective air-fuel ratio and integrates the deviation therebetween, smoothes the integrated values to absorb errors in control caused by variations in an injector or the like, and controls the air-fuel ratio in accordance with such integrated and smoothed values. The air-fuel ratio controller always controls the air-fuel ratio properly by stopping the smoothing of the integrated values when, for example, the detected oxygen content is disordered, and the detected values do not vary remarkably for more than a predetermined period.

摘要： A fuel controller for an internal combustion engine has a control unit which calculates the amount of fuel to be supplied to the engine by fuel injectors and drives the fuel injectors with a prescribed timing. The timing of the fuel injection is advanced at high engine speeds. The fuel injection timing is set such that the fuel injection is performed substantially in synchrony with the calculation of the amount of fuel to be supplied even when the fuel injection timing is advanced.

摘要： A fuel control system for an internal combustion engine capable of correcting an inlet air flow rate, used for the computation of a fuel injection, in consideration of a blow-back flow rate. The inlet air flow rate is detected by a hot-wire type sensor and sampled by a control unit. The control unit determines whether or not the sampled inlet air flow rate has reversed twice its gradient from the negative one to the positive one between predetermined crank angles of the engine and computes the blow-back flow rate subtracted from the inlet air flow rate.

摘要： A system and a method for controlling fuel supply to an internal combustion engine are disclosed in which excessive supply of fuel to the engine is effectively prevented in a most reliable manner particularly at the time of engine deceleration. To this end, a reduction in the amount of intake air sucked into an engine per intake stroke is sensed, and the amount of fuel supplied to the engine is reduced when there is a reduction in the intake air amount sucked into engine per intake stroke. The amount of reduction in the fuel supply is changed in accordance with at least one of the number of revolutions per minute of the engine and the amount of intake air sucked into the engine per intake stroke.

The system is equipped with a Karman vortex air-flow sensor, at least one injector for feeding a fuel into an internal combustion engine, a controller for controlling the quantity of the fuel, which is to be injected, on the basis of intake air flow rate information from the air-flow sensor, and at least one operation parameter sensor. The controller also includes at least one additional control unit which serves to correct the quantity of the fuel, which is to be fed into the engine, in accordance with at least one operation parameter from the operation parameter sensor and frequency information outputted from the air-flow sensor. The quantity of the fuel, which has been determined based on an output from the air-flow sensor, is corrected by the controller in accordance with changes in kinematic viscosity of the atmospheric air.
